The simple definition of a force is a push or a pull. Forces are the agent of change. Forces speed things up, slow things down, push them up hills and around corners. Forces can distort objects by compressing, stretching, or twisting. Friction can have a negative impact on the motion of an object or it can have a positive effect. This section will deal with the study of forces, the dynamics of motion.
